As seen in FIG. 7, the base member 12 includes the first internal spaceS1 and a third internal space S3. The third internal space S3 isdisposed over the hydraulic unit 22 at the grip portion 12G when viewedfrom the first direction D1 in the mounting state of the bicycleoperating device 10. The operating member 14 includes a fourth internalspace S4, a fifth internal space S5, and sixth internal space S6. Thefourth internal space S4 is disposed near the proximal portion 14A. Thefifth internal space S5 is disposed at the receiving portion 41. Thesixth internal space S6 is disposed near the distal portion 14B.Specifically, the fourth internal space S4 is disposed closer to theproximal portion 14A than to the distal portion 14B. The fifth internalspace S5 overlaps with the second internal space S2 that the additionaloperating member 34 includes when viewed from the first direction D1.The sixth internal space S6 is closer to the distal portion 14B than tothe proximal portion 14A.

The first internal space S1, the third internal space S3, and the fourthinternal space S4 are disposed above at least part of the hydraulic unit22 when viewed from the first direction D1 in the mounting state of thebicycle operating device 10. That is, at least part of the hydraulicunit 22 is disposed below each of the first internal space S1, the thirdinternal space S3, and the fourth internal space S4. The first internalspace S1, the third internal space S3, and the fourth internal space S4are disposed farther from the free end 14FE of the operating member 14than at least part of the hydraulic unit 22 when viewed from the firstdirection D1. That is, at least part of the hydraulic unit 22 isdisposed closer to the free end 14FE of the operating member 14 thaneach of the first internal space S1, the third internal space S3, andthe fourth internal space S4 when viewed from the first direction D1.The first internal space S1, the third internal space S3, and the fourthinternal space S4 are disposed in the upper side US.

Conversely, the second internal space S2, the fifth internal space S5,and the sixth internal space S6 are disposed below a whole of thehydraulic unit 22 when viewed from the first direction D1 in themounting state of the bicycle operating device 10. The second internalspace S2, the fifth internal space S5, and the sixth internal space S6are disposed closer to the free end 14FE of the operating member 14 thanat least part of the hydraulic unit 22 when viewed from the firstdirection D1. The second internal space S2, the fifth internal space S5,and the sixth internal space S6 are disposed in the lower side LS.

In the bicycle operating device 10 illustrated in FIG. 7, at least oneof the wireless communicator WC1 and the power supply PS1 is disposed inat least one of the first internal space S1, the third internal spaceS3, and the fourth internal space S4. In a case where at least one powersupply (e.g. the power supply PS1) is disposed in at least one of thefirst internal space S1, the third internal space S3, and the fourthinternal space S4, as described in the first embodiment, any wirelesscommunicator (e.g. the wireless communicator WC1) may be disposed in anyof the first to sixth internal spaces S1 to S6. Further, in a case whereat least one wireless communicator (e.g. the wireless communicator WC1)is disposed in at least one of the first internal space S1, the thirdinternal space S3, and the fourth internal space S4 any power supply(e.g. the power supply PS1) may be disposed in any of the first to sixthinternal spaces S1 to S6.

In a case where the wireless communicator WC1 is disposed at the basemember 12 (e.g. in the first internal space S1 or in the third internalspace S3), the wireless communicator WC1 is preferably disposed to facetoward the transverse center plane CP 2 (see FIG. 2). FIGS. 8 and 9illustrate an example of the bicycle operating device 10 in which thewireless communicator WC1 is disposed in the third internal space S3.Specifically, FIG. 8 is a cross-sectional view of the example of thebicycle operating device 10 taken along line VIII-VIII of FIG. 7. FIG. 9is a top view of the example of the bicycle operating device 10 as seenfrom the above in the mounting state of the bicycle operating device 10.In FIGS. 8 and 9, the power supply PS1 is also disposed in the thirdinternal space S3, but the power supply PS1 may be disposed in one ofthe first, second, and fourth to sixth internal spaces S1, S2, and S4 toS6.

As seen in FIGS. 8 and 9, the first direction D1 is a bilateraldirection including a first unilateral direction D1 (e.g. the leftwarddirection D1) and a second unilateral direction Dri (e.g. the rightwarddirection Dri). The second unilateral direction Dri is a reversedirection of the first unilateral direction D1. The base member 12includes a first lateral surface LS1 and a second lateral surface LS2.The first lateral surface LS1 faces toward the first unilateraldirection D1. The second lateral surface LS2 faces toward the secondunilateral direction Dri. The first lateral surface LS1 is closer to thetransverse center plane CP than the second lateral surface LS2 in thefirst direction D1. Preferably, the wireless communicator WC1 isdisposed between the first lateral surface LS1 and the second lateralsurface LS2 in the first direction D1. The first lateral surface LS1 iscloser to the wireless communicator WC1 than the second lateral surfaceLS2 in the first direction D1.

Further, as seen in FIGS. 7 to 9, at least part of the hydraulic unit 22overlaps with at least one of the wireless communicator WC1 and thepower supply PS1 when viewed from the above in the mounting state of thebicycle operating device 10. Similarly, at least part of the hydraulicunit 22 overlaps with at least one of the wireless communicator WC1 andthe power supply PS1 when viewed from a handle tangential direction HTDparallel to the clamp center axis CCA. At least part of the hydraulicunit 22 overlaps with at least one of the wireless communicator WC1 andthe power supply PS1 when viewed from a hydraulic unit based verticaldirection HVD perpendicular to the first pivot axis A1 and the hydraulicunit center axis HCA. Accordingly, it is possible to make at least oneof the base member 12 and the operating member 14 thin in the firstdirection D1. Therefore, a user can easily grip at least one of the basemember 12 and the operating member 14.

In a case where the wireless communicator WC1 is disposed at theoperating member 14, the wireless communicator WC1 is preferablydisposed in the sixth internal space S6, because the sixth internalspace S6 is closer to the additional component BC2 than the fourth andfifth internal spaces S4 and S5 to improve wireless communicationperformance. In this case, as described above, at least one power supply(e.g. the power supply PS1) is disposed in at least one of the firstinternal space S1, the third internal space S3, and the fourth internalspace S4 such that the at least part of the hydraulic unit 22 isdisposed below the power supply PS1 in the mounting state of the bicycleoperating device 10.

The communication controller CC1 may be disposed in a different internalspace (one of S2 to S6) from the first internal space S1. In a casewhere the bicycle operating device 10 comprises the plurality ofcommunication controllers, plurality of communication controllers may bedisposed in at least one of the first to sixth internal spaces S1 to S6.Further, at least one of the plurality of the communication controllers(e.g. the communication controller CC1) may be integrated into thewireless communicator WC1 as a single unit.

At least one of the electrical switches SW1 and SW2 may be disposed inat least one of the internal spaces S3 to S6 which are different fromthe first and second internal spaces S1 and S2. For example, theelectrical switch SW2 may be disposed in the fifth internal space S5 ofthe receiving portion 41 in place of the second internal space S2. Inthis case, the electrical switch SW2 overlaps with the additionaloperating member 34 when viewed from the first direction D1. A button ofthe second electrical switch SW2 protrudes from the receiving portion41. That is, the electrical switch SW2 is disposed to face theadditional operating member 34 in the first direction D1. In thisstructure, the electrical switch SW2 is configured to be activated bythe additional operating member 34 in response to the second inputoperation, which is described above.

Further, in a case where the power supply PS1 generates electric energycaused by the press of at least one of the electrical switches SW1 andSW2, the at least one of the electrical switches SW1 and SW2 maypreferably be integrated into the power supply PS1. Alternatively, theat least one of the electrical switches SW1 and SW2 may preferably bedisposed in an internal space in which the power supply PS1 is disposed.

The informing device INF1 is mounted to one of the base member 12, theoperating member 14 and the additional operating member 34. In theillustrated embodiment, the informing device INF1 is mounted to theadditional operating member 34. The informing device INF1 can be alsomounted to one of the base member 12 and the operating member 14 ifneeded and/or desired. The informing device INF1 may be disposed in adifferent internal space (one of S1, S3 to S6) from the second internalspace S2. Further, the informing device INF1 may be disposed in anapparatus mounted to the bicycle handlebar 2 which is different from thebicycle operating device 10 (e.g. a cycle computer). In a case where thebicycle operating device 10 comprises a plurality of informing devices,the plurality of informing devices may be disposed in at least one ofthe first to sixth internal spaces S1 to S6.

In a case where structures of the bicycle operating device 10 is appliedto the left control device 11 which is shown in FIG. 2, the left controldevice 11 has substantially the same constructions as those of bicycleoperating device 10, except that they are mirror images of each other,they will not be described and/or illustrated in detail here for thesake of brevity.

More specifically, the whole of thecylinder bore 24, the whole of the piston 26, and the whole of thereservoir tank 32 are disposed above the first pivot axis A1 when viewedfrom the first direction D1 in the mounting state of the bicycleoperating device 110.

Further, at least part of the hydraulic unit 22 is disposed closer tothe second end 12B than the first pivot axis A1 when viewed from thefirst direction D1 parallel to the first pivot axis A1.

The third internal space S3A is shaped differently from the thirdinternal space S3 in the first embodiment such that at least part of thehydraulic unit 22 is disposed below the third internal space S3A. Thefourth internal space S4A is disposed below the whole of the hydraulicunit 22 when viewed from the first direction D1 in the mounting state ofthe bicycle operating device 110.

Accordingly, the first internal space S1A and the third internal spaceS3A are disposed farther from the free end 14FE of the operating member14 than at least part of the hydraulic unit 22 when viewed from thefirst direction D1. That is, at least part of the hydraulic unit 22 isdisposed closer to the free end 14FE of the operating member 14 thaneach of the first internal space S1A and the third internal space S3Awhen viewed from the first direction D1. Further, the fourth internalspace S4A is disposed closer to the free end 14FE of the operatingmember 14 than at least part of the hydraulic unit 22 when viewed fromthe first direction D1.

Third Embodiment

A bicycle operating device 210 in accordance with a third embodimentwill be described below referring to FIGS. 12 and 13. The bicycleoperating device 210 has the same configuration as the bicycle operatingdevice 10 except for a hydraulic unit 122, a position of the first pivotshaft 20, a pivot pin 142, an operating member 114, an additionaloperating member 134, a shape of a third internal space S3B in the basemember 12, a shape of a fourth internal space S4B in the operatingmember 114, a positional relationship between a first internal space S1Band the hydraulic unit 122, and a positional relationship between thethird internal space S3B and the hydraulic unit 122. Thus, elementshaving substantially the same function as those in the above embodimentswill be numbered the same here, and will not be described and/orillustrated again in detail here for the sake of brevity.

As seen in FIGS. 12 and 13, the bicycle operating device 210 in thethird embodiment includes an operating member 114 which includes thehydraulic unit 122. In this embodiment, the first pivot axis A1 (thefirst pivot shaft 20) is arranged at a front portion of the operatingmember 114 when viewed from the first direction D1 in the mounting stateof the bicycle operating device 210. The first pivot axis A1 is arrangedcloser to the second end 12B than to the pommel portion 12P when viewedfrom the first direction D1. As seen in FIG. 13, the hydraulic unit 122comprises a cylinder bore 124 and the piston 26. The hydraulic unit 122comprises a reservoir tank 32 connected to the cylinder bore 124. Asseen in FIG. 13, the cylinder bore 124 is shaped as a hole in theoperating member 114. However, the cylinder bore 124 may be defined by ahydraulic cylinder which is provided in the operating member 114 andwhich is a different member from the operating member 114. Further, thereservoir tank 32 may be integrated into the cylinder bore 124.

The hydraulic unit 122 is disposed behind the first pivot shaft 20 whenviewed from the first direction D1 in the mounting state of the bicycleoperating device 210. That is, at least part of the hydraulic unit 122is disposed closer to the first end 12A than the first pivot axis A1when viewed from the first direction D1. Specifically, a whole of thehydraulic unit 122 is disposed closer to the first end 12A than thefirst pivot axis A1 when viewed from the first direction D1. The firstpivot axis A1 is disposed closer to the second end 12B than at leastpart of the hydraulic unit 122.

At least part of the hydraulic unit 122 is disposed above the firstpivot axis A1 when viewed from the first direction D1 in the mountingstate of the bicycle operating device 210. Specifically, in theillustrated embodiment, a part of the connecting rod 30 is disposedabove the first pivot axis A1 when viewed from the first direction D1 inthe mounting state of the bicycle operating device 210. However, anotherpart of the hydraulic unit 122 may be disposed above the first pivotaxis A1.

In the third embodiment, the base member 12 includes an operating memberactuating surface 46 under the first internal space S1B. The operatingmember actuating surface 46 pushes a top end 31 of the connecting rod 30toward the distal portion 14B of the operating member 114 when theoperating member 114 is operated to move from the rest position P11toward the operated position P12. An outlet port P3 of the hydraulicunit 122 is disposed closer to the distal portion 14B of the operatingmember 114 than the piston 26.

In the illustrated embodiment, the additional operating member 134 ismovably coupled to the base member 12. The additional operating member134 does not overlap with the operating member 114 when viewed from thefirst direction D1. Accordingly, the operating member 114 does notinclude the receiving portion 41 and the fifth internal space S5.

As seen in FIG. 13, the additional operating member 134 is pivotallymounted to the base member 12 via a rotational mechanism 135. Theadditional operating member 134 is rotatable about a third pivot axis A3which is parallel to the first pivot axis A1. The additional operatingmember 134 is rotatable about the third pivot axis A3 in a fourthmovable direction MD4 to accommodate the pivoting of the operatingmember 114. In this embodiment, the fourth movable direction MD4 is acircumferential direction defined about the third pivot axis A3. Thebicycle operating device 210 includes a pivot pin 142 defining the thirdpivot axis A3. The pivot pin 142 is secured to the rotational mechanism135. The additional operating member 134 is pivotally mounted to therotational mechanism 135 via the pivot pin 142.

The rotational mechanism 135 is pivotally mounted to the base member 12about a fourth pivot axis A4 which is non-parallel to the first pivotaxis A1. Accordingly, the additional operating member 134 is rotatableabout a fourth pivot axis A4. The rotational mechanism 135 may have thesame structure as a structure which the additional operating member 34and the electrical switch SW2 in the first embodiment constitute andwhich is illustrated in FIG. 5. In a case where the rotational mechanism135 may have the same structure as a structure which the additionaloperating member 34 and the electrical switch SW2 in the firstembodiment constitute, the electrical switch SW2 in the rotationalmechanism 135 is electrically connected to the wireless communicatorWC1. Alternatively, the rotational mechanism 135 may have a rotationalstructure that a conventional shift unit has. For example, therotational mechanism 135 may have a gear rotatable about the fourthpivot axis A4, a latch to position a rotational angle of the gear, and arotation sensor to detect the rotation angle of the gear. The rotationalmechanism 135 may further include a biasing member like the secondbiasing member 44 to bias the additional operating member 134 toward aspecific position (e.g. a rest position or an original position).

When the additional operating member 134 is pushed by a usersubstantially along the first direction D1 which is parallel to thethird pivot axis A3, the additional operating member 134 pivots relativeto the base member 12 about the fourth pivot axis A4 toward an operatedposition which is not shown in the drawings. Such pivotal movement ofthe additional operating member 134 relative to the base member 12 canbe referred to as the second input operation. The rotational mechanism135 is configured to receive the second input operation from a user togenerate a second control signal SG2 in response to the second inputoperation.

As seen in FIG. 13, the first internal space S1B is disposed over atleast part of the hydraulic unit 122 when viewed from the firstdirection D1 in the mounting state of the bicycle operating device 210.That is, at least part of the hydraulic unit 122 is disposed below thefirst internal space S1B. The third internal space S3B is shapeddifferently from the third internal space S3 in the first embodimentsuch that at least part of the hydraulic unit 122 is disposed below thethird internal space S3B. The fourth internal space S4B is shapeddifferently from the fourth internal space S4 in the first embodimentsuch that at least part of the hydraulic unit 122 is disposed below thefourth internal space S4B. The fourth internal space S4B is disposedcloser to the first pivot axis A1 than the hydraulic unit 122 whenviewed from the first direction D1. The fourth internal space S4B isdisposed closer to the proximal portion 14A than to the distal portion14B.

Accordingly, the first internal space S1B, the third internal space S3B,and the fourth internal space S4B are disposed farther from the free end14FE of the operating member 114 than at least part of the hydraulicunit 122 when viewed from the first direction D1. That is, at least partof the hydraulic unit 122 is disposed closer to the free end 14FE of theoperating member 114 than each of the first internal space S1B, thethird internal space S3B, and the fourth internal space S4B when viewedfrom the first direction D1. Further, the second internal space S2 andthe sixth internal space S6 are disposed closer to the free end 14FE ofthe operating member 114 than at least part of the hydraulic unit 122when viewed from the first direction D1.

Therefore, in the third embodiment, at least one of the wirelesscommunicator WC1 and the power supply PS1 is disposed in at least one ofthe first internal space S1B, the third internal space S3B, and thefourth internal space S4B. In a case where at least one power supply(e.g. the power supply PS1) is disposed in at least one of the firstinternal space S1B, the third internal space S3B, and the fourthinternal space S4B, any wireless communicator (e.g. the wirelesscommunicator WC1) may be disposed in any of the first to fourth and thesixth internal spaces S1B to S4B and S6. Conversely, in a case where atleast one wireless communicator (e.g. the wireless communicator WC1) isdisposed in at least one of the first internal space S1B, the thirdinternal space S3B, and the fourth internal space S4B, any power supply(e.g. the power supply PS1) may be disposed in any of the first tofourth and the sixth internal spaces S1B to S4B and S6. Other featuresare the same as those in the first embodiment.
